Non-Catalytic Rayleigh-Taylor Assisted Combustion Adapted to Exploit Non-Catalytic Rayleigh-Taylor Instability
Combustion processes are essential to engines and power generation. Many combustion devices operate under large, induced forces by arranging the combustion flow path to follow a partially circular geometry that induces centripetal acceleration on the reactants and products flowing through the combustor. These combustors mix the cold reactants and hot...
